Classification of Tea Aromas Using Multi-Nanoparticle Based Chemiresistor Arrays

Classification of Tea Aromas Using Multi-Nanoparticle Based Chemiresistor Arrays

Nanoparticle based chemical sensor arrays with four types of organo-functionalized gold nanoparticles (AuNPs) were introduced to classify 35 different teas, including black teas, green teas, and herbal teas. Integrated sensor arrays were made using microfabrication methods including photolithography...
